To all whomit may concern:

' Be itknown that I, Gnonor. ll. lsiirr, a citizen of the llnited States. residing at lYorcester. in the county of Iorcester and Commonwealth of Massachusetts, have invented anew and useful Imprm'ement in a "Feeding Mechanism for Gaslroduccrs, of

which the following is a. specification, ac-

1' companied bv drawings forming a part of the same, in which.

- Figure. 1 represents'a plan view of a gas producer embodying my invention. Fig. '2

is a verticai sectional view of the fcedin .mechanism on the plane of the broken line 2-2. Fig. l. and Fig. 3 is a'detached perspective view of one of the adjustable coal distributers.

Similar referencecharacters refer to similar parts in the different figures.

My present llU'CDtiOII relates to the coal feeding mechanism of a gas producer. having for its objects to accomplish a more uniform and etiicient distribution of the coal to the gas producing chamber and to bring the distribution within the control of the oper shaped. to contain water to avoid the injurious etfects due to over heating". The cover 3 is provided with a series of openings 4 closed by covers 5. which are water sealed by the body of water 6 contained in the cover 3. The openings 4 allow the interior of the producing chamber 1 to he inspected to determine the condition of the fuel and to observe its distrilmtion. Mounted upon the cover 3 a plat form 7. upon which coal delivered through the hopper shaped opening 8 from the magazine 9.

Journaled in the platform T. concentricallyflwith the gas producing chamber. is a spindle 10. To he lower end of the spindle v lt'l'is attached a ratchet wheel 11. actuated by a pawl l2 pivotally attached to a reciprocatin'e" liai l l. The bar 13 ispivotally connectcd with a block 14 pivoted at 15 to a bracket in. block H is a .rod 17 having a handle 18 at Vertically adjustable in the lowered in the bloc-kit and held in position by a set screw 10. The lower end of the roll 14 15 connected by a huh-20 with an eccendriven by a belt pulley 24 through a hell; connection 25 with a suitable source of power. The vertical adjustment of the rod 17 in the block l-i varies the amount mfg-cciprocatin r movement of the bar 13. causing" the pawl 12 to slide over one or more t:

to the rotating spindlo ill. i'pon the 2 end of the spindle. l0 areattau-hcd blade which extend over the surface of the -z=-- form 7 and serve to push the coal tr: center of the platform toward, its

and. for this purpose. the blades v. crahly curved. as shown by the 'li '27. Fig. 1. and they are rotated in the d tiou ofthe arrow 28. Fig. 1. Near the periphery of the platform 7 are a series of openings, one of which i shown at; Fig. 9. said openin 1"- being in mine-- ment with similar opcniizrrs in the cove-113. one of which is shown at 30. Fig. 2. Mounted uponthcl platform 7 is a cover 31 havinga depending flange 3-2. which rests upon the platform T insidc'an upturned flange 33 on the edge of the platform 7. The cover 31 is also provided with an upturned tiaugre 3i forming a pan shaped receptacle for water. The cover 31 is also provided with a series of concentric openings, one of which shown at Fig: 2. in alinement with the openings 99 of the platform 7. The openings 35 are surrounded by an upturned flangeS, extending above the line of the water on the cover 31 and supporting a downwardly flanged cover 36, by which the cover is water 1 sealed.

'Dcpcnding fromthe under side of the cover 36 is a coal distributer' 3T, which is shown in detached perspective view in Fig. 3. The upper portion of the distributor 37 cross section. and is provided at its upper end with a flange 38 having a bolt hole 39 i lower end of the coal distributor is provided with an inclined chute 40 having, through a portion of its length. the side flanges -il.- 4!. The vertical semicircular section of the coal its upper end, by which it may he raised or trio strap 21 inclosin 9 an eccentric "22 car ried upon a rotating" shaft- 23. which is vertical and substantially semicircular in b) which it is attached to the cover 36. The

according to the speed it is dcsiredto .\'e

distributor-37 extends downward through the openings 35' and 29 and is maintained, by its attachment to the cover 36, near the peripheries of the openings 35 and 29. The inclined chute 40 proiects downward at an oblique angle through the. opening 30 in the 1' cover 3; .The opening 39 is inclosed by a flaring flange 42, forming an inverted hopper shaped space for the free delivery of coal from the chute LO-into the gas producing chamber. The upper end of the flange 42 is cylindrical and is provided with. an interior shoulder -13, which supports the depending flange 44 inclosing the opening 29. The magazine 9 is a cylindrical shell which rests'upon the cover 31 concentrically with 1e hopper shaped opening 8. The cover 1 is'turned upwardly at 45 to form, a flange which is inclosed by the lower end of the magazine 9. The'fiange 45 -is then bent I downwardly at an oblique angle to form the hopper shaped opening 8.

The operation of my improved feeding mechanism is as follows :-.Coa-l contained of'openings 29.

the openings 29 it is caught upon the inclined chute 40, from which it slides at an oblique angle and becomes distributed over the mass of fuel in the gas producing chamher 1. An examination of the gas producing chamber, which may be made by removing either ofthe'covers 5 or 36, will disclose thedistribution of coal and, ifthis is not sufiiciently uniform, it may be. varied by rotating the covers 36 on their supporting flanges 35 thereby swinging the coal distributors 37 and changing the direction of the inclined chutes. An adjustment of a suilicient number of covers 36 is made to effeet a uniform distribution of coal over the incandescent mass of fuel in the gas producing chamber. If it be foundthat the combustion of fuel is proceeding in certain spots more rapidly than in others, the appropriate coal distributersare rotated 'in their respective openings to cause their inclined chutes to deliver an increased supply of coal thereto. The formation of air fines or pipes in the mass ofjfuel is thereby avoided and a uniform combustion throughout the-entire males of fuel is maintained.

he magazine 9 is water sealed at its lower end, as are also the covers 5 and 36.

The joints between the flanges and 33 and the flanges 42 and 4A are luted. The cover 3 and the operative mechanism mounted thereon-are protected from excessive heat by the body of-Water 6. The platform 7, cover 31 and magazine are individually or col- -lectively removable without the use of, bolts, .1

forming a simple and inexpensive construc tion.
